Qusetion 1. The different traits within a population are caused by option for answer 1. genetic variety, 2. natural selection, 3. pollution. Due to these differences the best traits in the population for survival will show up more frequently due to 1. genetic variety, 2. natural selection, 3. pollution. Question 2. In a new environment, traits for successful survival and reproduction become more common and traits that do not support survival become less common.
1. True
2. False

i think it is dna, i'm not totally sure but i think it might be.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

option c is the correct answer.
